Ah, that's a great question! Christmas tree lights can be so much fun, but they can also be quite a headache when they start blinking. The good news is that there are a few things you can try to make them stop blinking. First, make sure the lights are plugged in securely. If they're loose, they may not get enough power and start blinking. Next, try swapping out the bulb that's blinking. It's possible that one of the bulbs is faulty and causing the problem.
